feel sick and headachey. have been tailing off feeding for 2 weeks now as have very little milk and baby is on formula. didn't feed 6pm or 10pm last night. fed tiny bit from one side this am at 7. haven't fed since. now starting to feel really awful. breasts are a bit tender but no more than usual. not hot or swollen. can't feed the baby now as have eaten dairy and wheat products today and she is intolerant to both. should i pump? or am i just overtired after knackering day with 3 month old?
